Hi everyone,My kids (1 and 4) have taken up on both riding the (now 12V) quad at the same time. You could hear the gears grind but I still couldnt get them to stop. Long story short, the quad no longer moves. The motor spins, but the wheels don't.

I was wondering if there is anyone selling parts in Quebec, Canada, or what could be a good source online. While I'm at it, is there a good upgrade I should consider?
